Title: Improvements in universal joints
Inventor: GRUNDY CLIFFORD
IPC: F16D3/40
Filed: 1959-04-20
Abstract: 913,012. Universal joints. MOTOR GEAR & ENGINEERING CO. Ltd. March 31, 1960 [April 20, 1959], No. 13439/59. Class 80 (2). To allow maximum misalignment of a Hooke's joint comprising forks 10, 11 secured to adjacent shaft ends and formed with arms 10a, 11a pivoting at right-angles on a central cross 24 &c., the inner edges of the arm roots are cut away as at 28 to receive the outer corners of the arms of the other fork. The angle through which the joint can be deflected is thus increased without so weakening the fork arms as to limit the maximum torque that can be transmitted. Further, to prevent the free ends of the fork arms engaging the bottom of the space between the opposite fork arms, this space is milled out to the shape of a truncated cone 32. The central cross is formed by a spindle 15 pivoting in the fork arms 10a and two bushes 16, 17 at rightangles thereto pivoting in the fork arms 11a, a screw 20 passing through the bushes and a transverse hole in the spindle to hold the parts together. A part-spherical block 24 within which the spindle 15 &c. is mounted has four bearing faces 25 adjacent the inner sides of the fork arms 10a, 11a.

Patent GB-905643-A (GB)
Title: Improvements in devices for transferring values of indications in accounting machines
Filed: 1960-04-21
Abstract: 905,643. Statistical apparatus. COMPAGNIE DES MACHINES BULL. April 21, 1960 [April 29, 1959], No. 14107/60. Class 106 (1). In a statistical machine the input to and output from an accumulator is by way of the same conductor and pluggable connections are made from this conductor to input and output means. Fig. 4 shows three accumulators TD, TI and TC, the first for accumulating debit values read from grouped cards sensed at LT, the second being shown to illustrate how a number of accumulators can be interconnected in a chain and the third accumulates credit values. For each accumulator there is a corresponding printer ID, II, and IC and a punch PD, PS and PC which print and punch on different areas of a list sheet and a summary card respectively. Cards are sensed at LT in succession, debit values being indicated by a control hole which when sensed, routes the data to the debit accumulator TD. Pluggable connections are shown by a full and a broken line together. The accumulators have a number of stages each of which is connected with corresponding stages of the other accumulators as shown. Input to each stage is in the form of a pulse train, the number of pulses being equal to the entered digit which are applied from conductor C1, C2 or C3 via contacts CE1, CE2, or CE3 to a stepping coil ETD, ETI or ETC to advance a switch arm. Upon read-out a similar pulse train is transmitted by the switch arm from the contact stud with which it is in engagement, via a contact bar BRD, BRI or BRC via contact CB1, CB2 or CB3 to conductor C1, C2 or C3. The read-out train may represent the real contents of the accumulator or the complement for subtraction. In operation contacts CRL, CR1 and CR2 are initially closed. For credit values contacts CE3 and CRC are closed to enter the values into the accumulator TC and the printer IC which prints on the credit side of the list. Sensing of a " debit hole " causes contacts CE1 and CRD to close instead to connect up the debit accumulator TD and debit printer ID. At the end of a card group contacts CR1 and CR2 open and contacts CB1, CRD and CRP close so that the contents of the debit accumulator are passed to printer ID to print the debit total and punch PD to punch it on the summary card. Contacts CB3, CRC and CPC close to transmit the contents of the credit accumulator to printer IC and punch PC. The balance is worked out by re-closing contacts CR1 and CR2 and closing contacts CB3 and CE1 so that the contents of the credit accumulator are read-out and entered in subtraction into the debit accumulator TD. If there is a debit balance contact CRD closes to allow it to be printed in the debit column of the list and contact CRS closes to punch it on the summary card together with a debit hole. A credit balance is passed to printer IC and again punched in punch PS but without the debit hole. Accumulator decades comprising relay chains may replace the selector switches and route switching may be by transistors or photo-resistant elements instead of by relays.

Abstract: 814,634. Cold-cathode tubes. WESTERN ELECTRIC CO. Inc. May 3, 1957 [May 7, 1956], No. 14170/57. Class 39(1). The ionization time of a gas discharge tube is reduced by means of an r.f. discharge maintained inside the envelope at a region remote from the main gap. The r.f. discharge virtually eliminates the statistical delay time without substantially affecting the ionization potential of the main gap. The tube shown is described in Specification 686,427 and has a negative resistance characteristic. The main gap defining electrodes 11 and 12 are connected to a D.C. or pulse source 16. Two wires 14 connected to an r.f. source 15 pass adjacent to the envelope 10 and establish an r.f. discharge in the envelope. The r.f. energy may be capacitively coupled into the envelope by way of two spots of high resistance glass in the glass wall of the envelope 10 or by way of two metallic spots on the inner wall of the envelope. The metallic spots may be superimposed on the high. resistance glass spots. Graphs are given showing the relationship between the spacing between the wires 14 and the r.f. voltage necessary to establish the r.f. discharge inside the envelope and the relationship between overvoltage applied to the electrodes 11 and 12 and the time required to establish a stable main discharge in the tube. Specifications 704,108, 779,984 and 788,837 [All in Group XXXIX] also are referred to.
